It’s not only obvious, it’s seemingly simple: call 911 when someone needs medical help immediately. But what about when it’s complicated, like an underage friend who’s had too much to drink, or any age friend or relative who has taken a drug illegally?

Gov. Chris Christie and the state Legislature did the right thing when they enacted the Overdose Protection Act this year, extending protections already offered in New Jersey to the person who seeks medical help for underage consumption of alcohol, along with the victim.

Now those who seek medical help for an underage drinker, or any age substance abuser, can’t be charged with a possession or use offense or probation violation.

Hunterdon County Prosecutor Anthony Kearns III thinks that the Overdose Protection Act already saved a life in Hunterdon, when a 20-year-old’s friend called for help.

These laws don’t condone underage drinking, or illegal drug use. They do require that callers remain with the victim and answer questions for emergency responders. And it protects healthcare professionals and others who administer overdose antidotes in life-threatening cases.

Spread the word. It may not be an easy conversation to have, and may be greeted with “I’d never” protests. But none of us can see the future and the knowledge is good to have, just in case.
